What is Reaction to Fire Testing?

Reaction to fire testing examines the combustibility, ignitability, heat evolved, spread and smoke emission properties of materials. Such testing quantifies their role in the progression and propagation of fires. This focus is distinct from fire resistance testing, which validates a material’s capacity to withstand fire passage. Quantifying the initial phases of fire development holds paramount significance in ensuring safe evacuations, whether in a vehicle or building and is required by various building and vehicle regulations.

What is Fire Resistance Testing?

Fire resistance testing examines the ability of a product or system to resist the passage of fire through an element or weaken the element to an extent it cannot perform its structural or other intended function. Fire resistance is determined through full scale destructive fire testing, designed to replicate the product or systems intended end use application and in some cases structurally loaded. Quantifying the fire resistance behaviour of building products, systems and materials holds paramount significance to the safety, stability and response of a building or vehicle to a fire and is required by various building and vehicle regulations.

What is Bushfire testing?

Bushfire testing is a broad term that could include many and varied experiments related to the movement of fire within the landscape, the impacts of fire and smoke on people and the environment to the response of building products and systems used in home to the effects of bushfire. CSIRO Fire Technology Laboratory provides testing services  related to the response of building products and systems used in home to the effects of simulated bushfire. Quantifying the bushfire behaviour of building products, systems and materials holds paramount significance to the safety, stability and response of a building exposed to bushfire and is required by various building regulations.

Building Product and System Assessments in Australia

What are assessment Reports?

A fire assessment has been called an “opinion”,  “letter of opinion”, “Report from NATA accredited laboratory”, “report from an Accredited laboratory” and other things.  The current term that CSIRO uses is “Assessment”. These documents are described as a report that includes a comprehensive study based on test reports that examine the impact of minor variations to tested products or systems on their fire performance. These reports are:

  • Generally focused on the building industry
  • Intended as “Deemed to Satisfy Solutions” rather than Performance Solutions in the context of the Australia Building Regulations (NCC)
  • Generally, prepared to meet requirements of various NCC clauses including A5G3, A5G5, A5G6 and A5G7 as being ba ”report from an Accredited Testing Laboratory”

How are they put together?

CSIRO’s assessment reports vary in scope, ranging from simple evaluations of minor product modifications or variations to a test method to labyrinth analysis based on many test reports and utilising various engineering methodologies. These assessments often involve interpretation and interpolation of results from a test to evaluate the impact of various factors in construction or product design has on its performance. They include a clear statement of the construction or product being assessed and appendices summarising the facts relied upon and a detailed discussion on the basis of the conclusions made.

Assessment or Test first?

In instances where direct fire testing of every possible combination and configuration (minor variation) of a product is not feasible, the CSIRO assessment team can provide the following fee based services

  • provide an assessment after the testing is completed or
  • structure a logical test program before testing is done to address the variables and behaviour expected for the various forms of construction the client wishes to commercialise.

What are the key types of services to request?

Our fire assessment team offers the following services in our area of expertise:

  • Assessment Report – Comprehensive fire assessment reports that address variations to fire resistance, reaction to fire, and bushfire attack levels of products.
  • Test report confirmation – Confirmation of fire performance of a product or system to the extent possible to current Australian standards, based on reference to test reports from accredited test laboratories that were tested to test standards other than the current versions.
  • Test Program Consulting – Consultation on new product ranges or systems to identify the essential tests needed for regulatory compliance.

Use of Expired CSIRO Opinions/assessments

CSIRO opinion/assessment reports include 5 year validity period, CSIRO has been asked from time to time about the use of expired CSIRO opinion/assessment reports in conjunction with Performance solutions (or the like) for the compliance of new or upgraded buildings with materials manufactured/supplied/installed/certified after the expiry of the CSIRO opinions/assessment report.

CSIRO does not support the use of expired opinions/assessments for demonstrating compliance after the opinions/assessments expiry date. CSIRO opinions/assessments may expire for various reasons including the following. In such circumstances, the conclusions of the report be invalidated and outside the control of CSIRO;

  1. the client may have refused to confirm the specification of the product has not changed since the referenced tests occurred and/or the product has changed (requested at renewal date).
  2. CSIRO may have new knowledge and experience in the area of the opinion/assessment that could change or contradict its outcome, consequently, the sponsor/client/manufacturer may have chosen to not align the opinion/assessment in line with that knowledge and experience and let it expire.
  3. CSIRO may have new knowledge and experience on the subject of the opinion/assessment which could change or contradict its outcome.  As the opinion/assessment is expired and the sponsor/client/manufacturer and report reader may therefore be unaware CSIRO may no longer support the outcomes stated in the opinion/assessment.
  4. Where the report has expired, and one of the above items occurs CSIRO has no reason to revise update or correct expired opinions/assessments unless requested by the opinion/assessment sponsor.

There is no way the reader of an expired CSIRO opinions/assessments can be aware of any of the above issues and as such CSIRO does not support the use of expired CSIRO opinions/assessments demonstrating compliance after the opinions/assessments expiry date.

Should the subject of an opinion/assessment need to be relied upon for building or construction or compliance works for materials supplied after the expiration of the assessment or opinion, the assessment or opinion will have to be updated. Practically this updating process can only be requested by the sponsor of the opinion/assessment.

Should the subject of an opinion/assessment need to be relied upon for building or construction or compliance works undertaken before the expiration of the opinion/assessment CSIRO does not see a reason for the extension of the validity of the opinion/assessment to support that installation.

We trust the above information provides users of CSIRO opinions/assessments the confidence of when to use them and when the sponsor of the opinion/assessment should seek a revalidation of the report.
